BOZEMAN — Newly hatched pallid sturgeon are dying in an oxygen-depleted zone of Fort Peck Reservoir after hatching in the Missouri River and drifting downstream to the lake, according to recent research.
A new study from a Montana State University-led team has determined the cause of the endangered pallid sturgeon's failure to successfully reproduce in the Missouri and other similar river systems.
New research from an Montana State University-led study has detailed an oxygen-depleted "dead zone" that kills of hatched pallid sturgeon embryos where the Missouri River enters Fort Peck Reservoir.
The January 2015 edition of the journal Fisheries features pallid sturgeon on its cover and contains a paper detailing MSU-led research that uncovers the cause of the endangered species' decline in the upper Missouri River.
Guided by lessons learned during the response to the 2011 oil spill in the Yellowstone River, Montana Fish, Wildlife and Parks officials are attempting to gather baseline data on the effects of Saturday’s oil spill into the Yellowstone near Glendive.

WILLISTON, N.D. — A bison skull and a car’s transmission are two of the strangest things Ryan Wilson has pulled up in a drift net from the bottom of the Yellowstone River while trying to capture wild pallid sturgeon.
A pallid sturgeon netted on the Yellowstone River near the confluence of the Missouri River is probably over 60 years old. Aging the fish is difficult, but there has been no documented successful reproduction of the wild fish since the dam creating Lake Sakakawea in North Dakota was erected in 1955.

Zac Sandness, a U.S. Fish and Wildlife technician, records where fish were netted on the Yellowstone River.
Tyler Berger, a U.S. Fish and Wildlife Service technician, releases a paddlefish from a drift net. Paddlefish spawn at about the same time as pallid sturgeon, so the more numerous fish are frequently caught as crews search for pallid sturgeon.
